I have stayed at both a couple of times. The Radisson is nice, with a great pool and nice rooms...but it can get crowded! The lobby on cruise day was crazy with excited cruisers. Even with designated shuttle times it was chaotic. There was yelling, pushing and almost a fight. One couple we met just took a taxi to the port. Our second time we had rented a car from Budget so we just dropped the car off there and took their free shuttle. I was just there for a class reunion and it was crowed the whole weekend.
Our stay at the Hampton Inn was actually nicer. We had a room on the 8th floor and the way the rooms are situated we had a view of the ocean from the front entry and from our balcony. Their pool is a normal hotel pool, free breakfast and a walkway to the beach. They didn't have the shuttle service when we were there but many took Art's shuttle. We rented a car again so we could look around. Their Concierge us a coupon for a free dessert at a restaurant on Merritt Island (where I grew up in the 60's). We felt like we were the hotel's only guests and they gave us so much attention. It is only 3 miles from the port so it's not that far. There also is an IHOP across the street for a late night snack...hot fudge sundae...ymm.
